Jessica- one of my moms swore her milk would not last as long as 48 hours.
If she pumped at all, she froze it immediately. Yes, it will smell sour,
but could it possibly be something she ate to give it a different odor?
Tell her to try to keep records. My milk always smelled like vomit if it
went bad. There was no doubt when it was old!
